>>35416976Gladly, although I'm not as versed in Aegislash.
But onto Blaziken. The motherfucker stands at 80/70/70 bulk, which isn't terrible, but comparing it to other Speed Boost users (Yanmega, Ninjask, and Scolipede), it's passably bulky and unlike all the others, it isn't whittled down by Rocks as bad on a swap.
It has pretty solid offenses of 120/110 in base and 160/130 in Mega. Oh right, the Mega. If we're talking bulk now we've got a survivable but not wallworthy 80 across the board.
This means Blaziken is more likely to get off more than one Speed Boost, and it's fairly safe to assume it can. If it's an SD set, by turn 3 you'd better have Priority or you're right fucked from a +2/+2 momentum machine that's not slowing down.
Now we get into the playstyle. In OU, Blaziken will always run bulky. Why? Because it can afford to set up better and after two turns it's golden even with minimal speed investment, so you may as well let it take a few more hits and make Super Effective STAB a requirement to OHKO it.
Base Blaziken at +2 Speed with 4 EV's? Hits 394 Speed. That ties with Crobat. Another Protect and add another 50% from the base on top of that for a total of 492 speed. Nothing without a scarf or a boost of its own is outspeeding it. Revenge killing requires Priority now.
And Blaziken. Hits. Hard.
+2 252+ Atk Blaziken Flare Blitz vs. 252 HP / 252 Def Mew: 321-378 (79.4 - 93.5%) -- guaranteed 2HKO after Leftovers recovery
+2 252+ Atk Blaziken-Mega Flare Blitz vs. 252 HP / 252 Def Mew: 397-468 (98.2 - 115.8%) -- 87.5% chance to OHKO after Leftovers recovery
It doesn't even need to use a Life Orb to destroy whatever it hits neutrally. If rocks are up it's basically GG.
